Mean Chef, this is probably one of the best crumbcakes that I have ever made!... buttery rich and loaded with my favorite fruit, blueberries, the fruit added to the crumb topping makes it extra special...we had this warm out of the oven, topped with icecream, yummmmmm!... I will be making this again and again!... thanks so much for sharing...Kittencal:)
